2. INTRODUCTION • According to Papadopoulos. , Gorgolewski the energy efficient renovation
of existing buildings is an important tool for the reduction of energy
consumption in the building sector.
• According to Martinaitis building renovation projects, whose feasibility is
assessed only with regards to energy efficiency, should be considered the
result of an “old attitde”.
• Recently, more attention is paid to sustainable, complex renovation
satisfying integration of social, technical, economic, ecological needs of
various stakeholder groups. Renovation and its impact to urban
development in search for the best possible solutions receives more and
more attention in various countries.
• Zavadskas, Kaklauskas, Raslanas integrate various IT supported knowledge
management, decision support, expert models for management of building
life cycle and assessment and optimisation of renovation projects.

3. THECONCEPTOFSUSTAINABLE
HOUSINGRENOVATION
• The definition given by the European Commission states: Sustainable
Development stands for meeting the needs of present generations without
jeopardizing the needs of futures generations – a better quality of life for
everyone now and for generations to come.
• It offers a vision of progress that integrates immediate and longer-term
needs, local and global needs and regards social, economic and
environmental needs as inseparable and interdependent components of
human progress.
• The issues of integral sustainable renovation of housing have been
intensively tackled for years in the countries of Central Europe and in
other: Austria, Switzerland, Germany and the Netherlands.

4. PRINCIPLES&GOALSBASED
ONDIFFERENTDOCUMENTS
Baldwin presents the following main
goals of sustainable building:
Sitar presents the following integrated
sustainable renovation principles:
1. Minimization of climatic changes
and risks to human health and
biodegradation in consequence of
economic activities
1. Improvement of living conditions and
provision of user-friendly apartments,
increasing flexibility of the whole building
concept and its parts according to the
current and future needs of inhabitants.
2. Optimal use of non-renewable
(finite) resources, i.e. energy, land,
minerals and other natural resources.
2. Decrease of energy use and related
building operational expenses.
3. Employing renewable resources
such as solar energy for heating of
houses, wind and water for energy
accumulation. Using wood as the
main construction material.
3. Increased use of environment-friendly
materials and renewable energy sources
4. Building objects which will grant
future generations satisfaction of
their needs in the domain of quality,
durability, flexibility, adaptability and
urban planning.
4. Economically favourable and innovative
planning, construction and measures.

5. KNOWLEDGEBASEDMODELFOR
USTAINABLEHOUSINGRENOVATIO
• Sustainability is based on satisfaction of three main groups of needs:
economic, social and environmental. Thus the base model is developed
taking these groups of needs as a framework for sustainable building
renovation.
• Housing renovation influenced by different stakeholder needs and project
efficiency influenced by micro and macro environment can be
characterized as a whole by various sources of explicit and implicit
knowledge.
EXPLICIT KNOWLEDGE
• Criteria system
• Measure units
• Meanings
• Primary significances
• Information about various
project alternatives.
IMPLICIT KNOWLEDGE
• Skills
• Qualification
• Experience
• Social
• Needs
• Formal And Non-formal
Procedures
• Intellectual Capital
• Traditions
• Emotions
• Comfort

6. MAINPRINCIPLES&METHODS
FORKNOWLEDGEBASEMODEL
• The proposed model was created on the following principles & methods :
1. Sustainability principle
2. Adequate reaction to rapidly changing environment
3. Multi-use principle
4. Principle of integration of various systems
5. Principle of reaction to real situation
6. Integrated analysis method
7. Principle of improvement of usefulness and price ratio
8. Functional analysis method
9. Principle of the degree of project efficiency dependence on stakeholders
and their aims.
10. Principle of integration of different sciences
11. Multi-variant design and analysis methods for projects.
